GRB physics with Fermi

Mikhail V. Medvedev

Radiation from GRBs in the prompt phase, flares and an afterglow is thought to be produced by accelerated electrons in magnetic fields. Such emission may be produced at collisionle…

Radiative cooling in relativistic collisionless shocks. Can simulations and experiments probe relevant GRB physics?

Mikhail V. Medvedev, Anatoly Spitkovsky

We address the question of whether numerical particle-in-cell (PIC) simulations and laboratory laser-plasma experiments can (or will be able to, in the near future) model realistic…

New Relativistic Particle-In-Cell Simulation Studies of Prompt and Early Afterglows from GRBs

K. -I. Nishikawa, J. Niemiec, H. Sol +8

Nonthermal radiation observed from astrophysical systems containing relativistic jets and shocks, e.g., gamma-ray bursts (GRBs), active galactic nuclei (AGNs), and microquasars com…

Jitter radiation images, spectra, and light curves from a relativistic spherical blastwave

Brian J. Morsony, Jared C. Workman, Davide Lazzati +1

We consider radiation emitted by the jitter mechanism in a Blandford-McKee self-similar blastwave. We assume the magnetic field configuration throughout the whole blastwave meets t…

Ab initio exchange interactions and magnetic properties of Gd2Fe17 iron sublattice: rhombohedral vs. hexagonal phases

A. V. Lukoyanov, E. E. Kokorina, M. V. Medvedev +1

In the framework of the LSDA+U method electronic structure and magnetic properties of the intermetallic compound Gd2Fe17 for both rhombohedral and hexagonal phases have been calcul…
